Known Health Benefits and Health Risks
Long-term studies of the vaginal ring are limited, but researchers expect that its health benefits and risks are like those of combined oral contraceptives (see Chapter 1 – Combined Oral Contraceptives, section on Side Effects, Health Benefits and Health Risks). Evidence to date has not shown adverse effects.
Medical eligibility criteria, guidelines for when to start, and helping continuing users for the combined ring are the same as for combined oral contraceptives and the combined patch. (See Chapter 1 – Combined Oral Contraceptives.)
